Specification:	The IUPAC name of C.I. Acid Red 1, disodium salt is disodium 5-acetamido-4-oxo-3-(phenylhydrazinylidene)naphthalene-2,7-disulfonate. With the CAS registry number 3734-67-6, it is also named as 2,7-Naphthalenedisulfonic acid, 5-(acetylamino)-4-hydroxy-3-(phenylazo)-, disodium salt; Acid red 1; Red 2G. The product's categories are dyes and pigments; organics. It is red powder or granules which is soluble in water and slightly soluble in ethanol. When heated to decomposition it emits toxic vapors of NO_x and SO_x. In addition, people should not breathe dust and avoid contact with skin and eyes. The other characteristics of this product can be summarized as: (1)#H bond acceptors: 11 ; (2)#H bond donors: 4 ; (3)#Freely Rotating Bonds: 6 ; (4)Rotatable Bond Count: 3 ; (5)Tautomer Count: 31 ; (6)Exact Mass: 508.993945 ; (7)MonoIsotopic Mass: 508.993945 ; (8)Topological Polar Surface Area: 202 ; (9)Heavy Atom Count: 33 ; (10)Complexity: 975. Preparation of C.I. Acid Red 1, disodium salt: Aniline which is diazotized is coupling with 8-acetyl-1-hydroxy naphthalene 3,6-disulfonic acid. Then, we can get the product by salting and refined. Uses of C.I. Acid Red 1, disodium salt: It is mainly used to dye all kind of natural fibres like wool, cotton and silk as well as to synthetics like polyesters, acrylic and rayon. And it is also used as edible red pigment. People can use the following data to convert to the molecule structure. 1.
